Solution Overview
Problem
Existing methods for generating carpet boundary images for ground sweeping robots result in rough images, hindering effective cleaning and positioning.
Innovation Solution
A map drawing method that scans the carpet boundary, merges initial boundary coordinates, divides the region into sub-regions based on a preset shape, and draws the boundary for a smooth, detailed map, enhancing cleaning and positioning accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing boundary scanning methods are used to generate carpet boundary images, then the scanning process is simple and fast, but the obtained boundary image is rough and lacks detail
Solution Approach 1:
The patent divides the merged region into multiple sub-regions based on preset shapes (rectangles, circles, triangles, etc.). Each sub-region is processed independently to generate boundary coordinates, which are then merged to form the final boundary image. This segmentation approach improves boundary image quality by allowing detailed processing of each sub-region while managing complexity through systematic division of the overall process.
2Manufacturing precision
If the boundary of the surface medium region is scanned directly to generate the map, then the process is simple, but the obtained map has a rough boundary and lacks detail
Solution Approach 1:
The patent performs preliminary actions by first dividing the merged region into sub-regions and generating boundary coordinates for each sub-region before final map drawing. The boundary coordinates of sub-regions are merged to create a refined boundary image. This preliminary processing ensures smooth boundaries and detailed maps, with the time investment offset by the improved quality for subsequent cleaning and positioning operations.

AI summary
Provided are a map drawing method, a map drawing device, a computer-readable storage medium and an electronic apparatus. The map drawing method comprises scanning a boundary of a surface medium region to generate an initialized region; merging boundary coordinates of the initialized region to obtain a merged region; dividing the merged region into a plurality of sub-regions according to a preset shape; and drawing the boundary of the surface medium region based on the sub-regions and the merged region to obtain a map of the surface medium region. The method can improve the detailedness of the drawn map of the surface medium region.
